Tor is an anonymous communication system that can protect our privacy, but it also provides a haven for criminals to avoid network tracing. Therefore, anonymous traffic analysis and classification is an important part of maintaining network security. Existing Tor traffic classification methods require a large number of labeled data, and the classification accuracy rate is not satisfied for practical...
How to embed the new observations (or samples) into the low-dimensional space is a crucial problem in non-linear manifold learning techniques. This issue can be converted into the problem of finding an accurate mapping that transfers the unseen data samples into an existing manifold. In this paper, a locality-constrained sparse representation algorithm is proposed to deal with the out-of-sample embedding...
Threaded debate forums have become one of the major social media platforms. Usually people argue with one another using not only claims and evidences about the topic under discussion but also language used to organize them, which we refer to as shell.

The idea of representing images using a bag of visual words is currently popular in object category recognition. Since this representation is typically constructed using unsupervised clustering, the resulting visual words may not capture the desired information. Recent work has explored the construction of discriminative visual codebooks that explicitly consider object category information. However,...
